Patented June 25,1912.

Application led August 28,' 1911. Serial No. 646,459.

To all whom t may concern.'

Be it known that IJ GILES M. TURNER, a citizen of the United, States,residing at Madison, in the county of Dane and State of l/Visconsin,have invented certain new and useful Improvements 1n' Means for.

Supporting and Drif'ving Electric Generators, of which the following isa .specification. l V

When a magneto or other current-generator is used to supply ignitioncurrent to an inter- Anal-combustion engine, it-vhas been customarilymounted uponsome portion of the bed or engine framework, and has beendriven by meansof a belt or gear connection with the crank shaft or somesecondary shaft of the engine. Diiiiculty has been experienced, however,in so locating and driving the generator, by reason of interference with`the Hy wheel, pulley, drive belt or the like, particularly in the caseof stationary engines which are usually supplied with a drivev pulleylocated at veither end of the crank shaft 'as specified by thepurchaser.

The'obJects Aof my invention are to obvviate the difliculty abovealluded to, and to eliminatev the expense incident to aspecial supportand drive. These objects I attain by utilizing either end of the crankshaftor some other suitable shaft of the engine.

The invention is applicable to automobile,`

marine, and stationary engines, but is here-l 1n shown, by way ofexample, as used in connection with a stationary motor.

1 designates an end ofV ariV engine shaft, as, for instance, the crankshaft. The magneto may be of anyi comnion or preferredv construction,that herein shown comprising an armature 2, an armature shaft 3, a hous-.qing 4 having bearings 5 and 6 for the arma- `ture shaft, 'and .fieldmagnets@ secured to the housing 4.'J The armature shaft 3 is at? tachedto the shaft Al in a suitable manner,

vas by providing said shaft 3 with a socket 8 to receivethe end of theshaft 1. Any preferred means, as, Afor instance, a. set screw 9, may beused to secure the socket 8 upon thel shaft 1. The magneto framework orvhousing`4 with the attached field structure is supported or suspendedupon 4 thearmature shaft orA journals, and is herein illustrated ininverted position.

Vhen intended for"use with an engine employing jumpspark ignition, meansmay Vbe provided for shifting thevbreaker lever 10 with relation tothe'breaker cam 1l. Since the cam is driven from the armature shaft, andthe circuit 'breaker lever is attached to the housing 4, it will be seenthat the spark may be advanced or retarded by adjustin the suspendedstructure about the axis of tie armature. Herein I have shown an arm 12secured toa portion ofthe suspended structure and having a portionl uponwhich a` weight 14- is adjustablyl mounted.

15- is a set screw for locking the weight 14 in the desired position.Itwill. be seen that the arm 12 and the weight 14 'constitute means forshifting the center of grav Aity of the magneto, and that the housing 4may be adjusted about the axis of the arma# ture by altering the centerof gravity 'of' the suspended structure. Suchshifting means may beomitted 'in the case of engines equipped for make-and-break ignition;

It will be 'apparentthat the magneto ma y be placed at either 'end ofthe crank shaft,

depending upon the location specified for the drive pulley by thepurchaser; and' that there is -nol supporting device or drive connectionto interfere with the drive belt or the o erative parts of the engine. Ic aim as my invention: l y 1. The combination .of an internalfcmi?Abustion engine anda current-'generator com' prising an Aarmature withitsjournalsP and a field.structure,"one ofthearmature journals beingaffixed to one end of thev engine" crankshaft, and the field structurebeing suspended from the armature journals.

2. The combination of'il'1,\.iut/ernalcomY bustion engine; a magnetocomprising a.l housing, an armature rotatably r'nountedA in the housing,and a field magnet attached to the housing;u and meansv for isingthearmature to and supporting it by one en ofthe engine crank shaft, thehousing sindA field magnet being suspended in inverted position. A

3. The combination of an internal-com# bustion engine and aCurrent-generator, the latterl Comprising a portion fixed to and Whollysupported by the engine crank-shaft, and the remainder of the generatorbeing freely suspended from Said shaft-supported portion, the suspendedportion having a relatively shiftable mass attached thereto.

4. The combination of an internal-oombustion engine and acurrent-generator, the' latter comprising a portion fixed to and Whollysupported by the engine crank-shaft, andthe remainder of the genera-torbeing freely suspended from said shaft-supported portion, av memberatt-ached to said suspended portion and located below the axis of thecrank shaft, and a weight adjustably att-ached to Ysaid member.

The combination of an internal-combustion engine, a magneto comprisingan armature attached to the engine crank shaft, a housing supported bythe armature, a circuit-breaker lever carried by the housing, a'circuit-breaker cam having a driving connection with the armature,and aiield magnet V,attached to the housing; and means for adjusting thehousing about the axis of the engine crank shaft.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
